Ingredients

1 cup all-purpose flour (spooned and leveled) 

1 teaspoon ground cardamom or 1 1/4 teaspoons pumpkin pie spice 

1 1/2 teaspoons baking powder 

1/4 teaspoon fine salt 

3/4 cup packed light-brown sugar 

2 large eggs 

2/3 cup vegetable oil 

1 tablespoon pure vanilla extract, divided 

2 cups grated parsnip (from 1 large peeled parsnip) 

8 ounces cream cheese, room temperature 

1/2 stick unsalted butter, room temperature 

1/2 cup confectioners' sugar 

Preparation

Preheat oven to 350 degrees. Whisk together flour, cardamom, baking powder, and salt. In a large bowl, whisk together brown sugar, eggs, oil, 2 teaspoons vanilla, and parsnip. Stir in flour mixture.

Line 12 standard muffin cups with paper liners. Divide batter among cups. Bake until a toothpick inserted in center of a cake comes out with a few moist crumbs attached, 18 to 20 minutes. Let cool completely in pan on a wire rack.

In a large bowl, with a mixer, beat cream cheese, butter, confectioners’ sugar, and remaining teaspoon vanilla until combined. Spread frosting onto cooled cupcakes.
